The remote Joomla installation is prone to three critical security
vulnerabilities.
Inadequate checks allows for users to register on a site when registration has been disabled.
Incorrect use of unfiltered data allows for users to register on a site with elevated privileges.
Incorrect use of unfiltered data allows for existing user accounts to be modified to include
resetting their username, password, and user group assignments.
